You could try but if it doesn't work out, it is too late.

I'd love to grow yams . I never ever see them here in NSW or Qld. In nZ they have the red orange and yellow. I'd be happy for any!!

Look up some seed selling websites to find some to buy. The guide here says to plant by Nov so you need to hurry.

Hi there, I have my yams in a bath tub, is there anything else I can plant in there with them?
29 Oct 19, Anon (New Zealand - sub-tropical climate)
You might be able to, but I'M a big believer that each crop has it's own space to grow. If you want to produce great yams why would you plant something else next to them to grab some of the fert, water etc. Each crop requires a minimum spacing between plants and between rows to produce a good. crop. Go and buy another bath tub, dig some ground up etc.
